In fluid simulation, the analysis and calculation of various forces within the fluid is critical, since the detailed motion of the fluid animated surface depends on the motion of the particles caused by various forces between the internal particles of the fluid. The vorticity constraint of the fluid is ubiquitous in the fluid, especially in the simulation of multiphase fluids, due to the different properties of the viscosity, density and other properties of the different phase fluids, resulting in more complex vortex generation. We mainly modify the vorticity method and the single-phase fluid simulation method in the previous grid simulation, optimize it, apply it to the simulation of multi-phase flow in the hybrid model to simulate the vorticity phenomenon, so that the fluid animations are more vivid and more realistic.
